MATHEMATICS 2 — SS 2017/18
- upon request (see my timetable and suggest me some days and times via e-mail)
- my office is in Sokolovská 83, 2nd floor, behind the glass door opposite to the staircase
There will be additional lessons on May 22 and 23 since there are no lectures and seminars on May 1 and May 8 (holidays) and no lecture and exercises on May 16 (Rector's day).
- Lecture - Tuesday 14:00 - 15:20 and Wendesday 11:00 - 12.20, O105 (Bárta)
- Seminar - Tuesday 15.30 - 16.50, O105 (Bárta)
- Exercises - Wendesday 12.30 - 13.50, O105 (Vlasák)
- Prerequisities. Knowledge of 'high school mathematics' is required (see this document for details) and Mathematics I.
- Literature. Script to download is comming soon.
Exams and grading
Students will be admitted to the oral exam only if the score from the first part (midterms, homeworks and written exam together) is at least 50 points. To pass the exam successfully, at least 20 points from the oral exam are required.
- midterm test: 10 points
- homeworks: 20 points (10 homeworks, 2 points each)
- final exam: 90 points (50 points written exam, 40 points oral exam)
Grading: The total score is obtained as the sum of the points from the oral part and the first part, where the score of the first part is reduced to 60 if it exceeds 60. The final grade depends on the total score as follows.
- 70-75.5 points ... "E"
- 76-81.5 points ... "D"
- 82-87.5 points ... "C"
- 88-93.5 points ... "B"
- 94-100 points ... "A"
Midterm test takes part approximately in the half of the semester. Students are asked to
within 30 minutes. Literature is allowed, electronic devices are prohibited. There are two attempts, the better result is taken into account.
Final Exam takes part in the examination period at the end of the semester. Students have three attempts to pass the final exam. It consists of a written part and oral part.
- find (and draw) the domain of a function of several variables and compute partial derivatives
- Written part. Students have 90 minutes to solve problems on
Lecture notes and other materials are allowed, electronic devices are prohibited.
- finding extrema of a function of several variables,
- matrics computations (system of linear equations, determinant, inverse matrix), and
- antiderivative (or Riemann integral).
- Oral part follows typically the day after the written exam. The oral part tests understanding the definitions and theorems and ability to apply them.
Each student should prepare answers within approximately 40 minutes. During the oral part only pencil and paper are allowed. Then the student should present answers and should answer additional questions. .
Here is the beamer presentation to download and the
list of definitions and theorems for printing (last update November 15, 2017).
